I have recently bought an external USB floppy drive to access many of my old floppies. There's a bit of a weird issue going on when trying to access the disks. For some reason OS X is reporting the capacity like it should, saying the capacity is 1.5MB, but when it gets to reporting the available space, it starts getting weird. Initially when I tried the drive, it said a disk had something like 178MB available. Today, it's saying the disks I am using have about 4.0-4.5MB available. For a few days OS X was accurately reporting the available space, but it's flipping out again. Anyone know why this is happening, and/or how to get OS X consistently reporting the free space correctly? All the disks are formatted using FAT12. I'm in the process of getting what I need off the disks, reformatting and relabelling them so they can be re-purposed.
